Specification Letters Annoncenmearannazyaagiatasmaintje patented Apr. .1, 1913.-

To all 'whom t may concern? .Be itv known that I, HEINRICH Raon- MANN, a subject of the Emperorof Austria- Hungary, residing at Haida, voheuu'a, in the Empire' of Austria-Hungary, ha've invented certain new and useful Improvements in and Relating to Atomizers, of which the followingis' a specification.

The present invention has for its object a. pump atomizer combined with a liquid reservoir. The knownpump atomizers of this kind present the defect that when the apparatns is horizontal the liquid is able to escape from the opening provided for the. passage of the piston rod'from the liquid reservoir .and alsofrom the atomizing aperture. Consequently the `knowndevices are not suitable for traveling, `more especially as the vibration and shaking arising in transport tends to causethe-piston rod to protrude so that it is liable to become deformed and injured.A

In accordance with the present invention the said defects are ,avoided owing to the factthatthe piston rod is retained in .its depressed positionbyan obturator closing' the aperture throughwhich the rod leaves the. reservoir. Owing to the'factvthat the opening through which the rod `leaves the liquid reservoir is closed, not only is theb piston rod prevented from protruding inopportunely but even when the .liquid is in communication with the atomizing aperture the escape .of liquid from this aperture is prevented because, as is known, it is possible for liquidito escape from a receptaele with la single-narrow .Opening unless there is ,an air inlet .at .another place.

A particularly advantageous arrangement is one in which the xing of the piston rod simultaneously .secures the suction valve in itsclosedxposition. This not only produces a double obturation bythe iixing means and the .suction valve but the latter acts directly' .as arirmly inserted stopper sov that in .an .atomizer of this kind .sensitive fand volatile yin its depressed position and '.ohturatmg the aperture throughywhich it ,passes is constituted by ,a screw cap fixed directly tothe .atomizing '"head. With Vthis construction,

,' When the'piston roti' is 4fixed the atomizing head constitutes a single rigid .whole .with the liquid reservoirA and the screw cap releves the piston rod from all bending strains due to lateral shocks. In the older forxusof atomizers laccidental escape of liquid. from the atomi'zing aperture is further facilitated owing to thefact that the valves of such atomizers which are manufactured in very' large .quantities cannot permanently form a,

liquid tight joint. In accordance with lthe invention this defect is obviated by capillary action. If, in endeavoring to follow this idea, it were attempted to form the spraying tube as an ordinary capillary' tube, the desired lresult would `not 'be attained ,as in this case the .spraying tube would present too small .a free' cross section to permit of the discharge of a suilicient quantityof liquid during the delivery stroke of the pis-y ton. Iiiaccordance with the invention this diiculty isiovercome by inserting a dong 'wire inthe spraying tube which slnetief cessively narrow so that an annlllir ,passage ofgre'at length is formed in the sprayi" tube, the total cross section of whichgis cently large to permit of the .discharge of the necessary quantity of liquidl during the delivery stroke of .the piston but'which' on the other hand is sonarrow that/it is impossible for liquidto issue ,automatically in opposition to the capillaryA action. "f he surprising fact has been noticed that an atomizer comprising this wire insertion does --not requlre Ya delivery valve atall because the cross section .of the pstonrelatively to the .cross section .of the Aannular passage ex'- isting around the insertedwire is so preponderating that the liquid-passes farmers speedily through the `suction valvle than the Outer -,air throu h the longannnlar passa e, so that, notwit standing the absence o 1 a delivery valve, a perfectly satisfactory suc-y tion of liquid takes place. By this means the cost of manufacture is largely reduced.

It is advantageous to utilize the wire in# 'sertion as a support for the atomizing plate or ,atom-izing cylinder. As is known, it frequentlyhappens -with atomizers of this kind .that the atomizing aperture becomes stopped.

Inthis case it isnecessary to unscrew the eel) Covering.4 the atomizillg cylinder or atomizingplate and containing the discharge f aperture. vin.,order to lprick the latter and clean the atomizing cylinder. In edectingf such a small roundbody as this cylinder.v

In accordance with the invention'this -defect is obviated owing to the factv that the' wire insertion in the spraying tube carries the atomizing plate at its extremity; if the cap is unscrewed the cylinder cannot be lost as .1t is lined to the wireand it can readily be cleaned. on all sides owing to its connection with the conveniently handled and stable body of the atomizer. v

Two embodiments of the invention are illustrated by way of example in the accompanying drawing, in which Figure 1 shows the atomizer ready for use. Fig-2 shows it closed. Fig. 3 shows the front. part of the spraying tube cfa second constructional form of theatomizer to a larger scale. Fig. 4 is a section on the line A-B of Fig. 3.

Referring to Figs. l and 2 a is the liquid reservoir, b the pump cylinder'in the reservoir and havingat its lower end a suction valve o, preferably in the form of a ball valve, as shown, and' al' is the piston in the` pump cylinder'. rlhe piston d is displaceable in the cylinder o by means of the hollow piston rod c serving as the spraying tube and which at its upper end carries'the atomizer.

head f. At its lower Aend this head forms a screw cap g which ts the screw 'socket on the reservoir a. it the piston d 'is depressed and the cap g screwed onto the socket 71, the opening through which the piston rod leaves the reservoir a is closed b the screw thread on the parts g and Finally the piston d' or a projection therefrom bears on the suction valve a and presses it firmly on its'seat so that a two-told securit' is atlorded against the escape of liqui as alread mentioned. Fig. 2 shows that in the closedY illustrated any lateral strains or shocks are taken entirely by the atomizer-head f and the cap g the slender piston rod e being completely protected. The piston rod e is bent over at its upper part and in the horizontal j length z' formed by this bending a wire 7c of 55.

corresponding length is inserted; 'llhis wire can be soldered atl for example.- Between the wire k and the innerwall ofthe len th of tube i a narrow annular passage there ore remains free through whichl the liquid forced up in the iston rod e is able to' pass. lfContrary to w at is the case in all known forms of atomizer no delivery valve need be provided.V The spirally channeled atomizer c linder m' is fixed to the end of the wire'4 k Ay soldering for emmple. Accordingly it the whole must position of the device there remesa cap n which contains the `discharge a ertur 0 is unscrewed the cylinder m cannot come lost. and is accessible on all sidestor cleaning.

' rlhe construction illustrated in Figs. 3 and 4 differs from thatshown in Fi s. l and 2 owing to the iact` that the wire is ri 'dly but detachably connected with the tule z'. With this object the wire' 1c comprises at the endl Aa tapering plate p which is tightly clamped in the tube fi.' The liquid is able to flow pastboth-sides of. the plate p and then, as in the irst construction, through the anv"and the tube.

if any deposit forms in the tube e which may take place especially at the bend at Z,

by means of a pair of pincers or the like the wire k carr ing the atomizing cylinder m can be with rawn irom'the tube e and the latter conveniently cleaned. Y v

@bviously instead of a wire a tube might be inserted in the spraying tube as the only result to be attained is-the formation oi a long narrow. passage which, however, as a present an adequateacross section.

any 'stir-atie kind of tanning pan or Acylinder can' be; employed.
